摘要
In order to provide an economical method for producing a weapon barrel, in which a considerable plasticisation of the barrel inner wall and thus of the twist profile is avoided when armour-piercing ammunition is shot, in particular in the case of an intense firing sequence, it is proposed not to introduce the twist profile of the weapon barrel into a barrel blank, the material of which has its end strength already as a result of hardening and tempering, but has a lower strength level (approximately 800-1000 MPa). Only once the twist profile has been formed by extrusion or hammering is the steel hardened and tempered to a predefined strength value >1000 MPa, and is the barrel blank that is provided with the twist profile mechanically processed further.
